Abstract
Titre. Dispositif de stockage et procédé de fabrication L’invention permet la réalisation d’une électrode (12), notamment pour des micro-batteries. L’électrode (12) est réalisée en plusieurs couches avec des étapes intermédiaires de masquage d’une première couche laissant exposer certaines parties de cette dernière pour produire ensuite un enlèvement de matière éliminant des défauts. Après suppression de la couche de masquage (16), la deuxième couche peut être formée. D’autres couches peuvent suivre de la même façon. Figure pour l’abrégé : Fig. 3Title. Storage device and method of manufacture The invention allows the production of an electrode (12), in particular for micro-batteries. The electrode (12) is made in several layers with intermediate steps of masking a first layer leaving certain parts of the latter exposed to then produce a removal of material eliminating defects. After removing the masking layer (16), the second layer can be formed. Other layers can follow in the same way. Figure for abstract: Fig. 3
